lMPR OVEMENT IN HOT-AlRREGl STERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom tt'may concern:

Be it" known that I, HUGH M. PHINNEY, of Boston, in the county of Sufi'olk and State of Massachusetts, have. invented Improvements in Hot- Air Registers; and l do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, isa description of my invention sufdcient to enable those skilled inthe art to practice it.

My. invention relates particularly to. the construction of the frames of hot-air registers (or that part of aregistcr which supports the movable valves or blades) and the connecting piece by which the register is joined to the hot-air, pipe, the invention also relating to the pivoted, connectionof the segmentwheel or lever that actuatesthe valve-blades.

In all hot-air registers, so far as I know, the box or flange-part of the frame that projects'from the inner or under side of the open register is composed of separate or distinct plates, which are fastened-together and to the register by screws, the employment .of the connecting-screws, the necessity of tapping nutthreads for reception of these screws, and the jointing of the abutting edges of these plates being not only a large item in the cost of construction of registers, but requiring the use of various tools and the work of skilled artisans; and the joints in such plates are always objectionable.

One part'of my invention consists in a register or register-frame, the projecting or blade-inclosing part or vertical flange of, which is formed of plates united to each other at their ends and to the open plate at their tops without joints; or, in other words,

are cast integral with each other and the main register-plate.

Hot-air pipes are always formed of sheet metal, (tinned sheet-iron being the metal generally employed) and the connection of the pipe and ther ister is effected by the intervention of a sheet-metal coupler or connector, one end of which is rectangular to receive the register-flange, and theother end of which is round and tubular to fit-into the end of the hotair pipe.

N ow, in putting up hot-air apparatus, the making of the round pipe requires no special skill, and may he, and generally is, thework of apprentices or of cheap or unskilled workmen but the connections always require such fitting, andare of such compound form, that to make and'apply them demands the labor cfa skilled workman.

v To obviate this, I make a connector to go with, and, if necessary, form a part of, every register, such connector having the square orbox-shaped flange to receivethe register-flange, the short projecting tubular flange to enter the end of the hot-air pipe, and,

the web connecting the two, these parts being made in one piece or cast solid or integral.

It is in a cast-metal connector-piece, having the register-flange and pipe-flange formed in one piece, connected by the web, that the second part of my invention consists. 3

The drawing represents a register and connector or coupling embodying my invention.

A shows a central vertical section of the same.

. B is a section on the line a; x.

0. denotes the main register-plate, consisting of the edge piece or horizontal flange 5, across which extends the open-work c.

d d are the end flanges, and

c e the side flanges, extending'vertically from the horizontal flange h, the connection of the flanges d (1 and e e to each other and to the flange I) being the connection efl'ected by casting them as one piece, leaving no parts to be united, no joints to be fitted, no screw-holes to be tapped, and no screws, rivets, or other fastenings to be applied.

f f denote the-side flanges, and

g g the end flanges of the hot-air pipe and registercoupling or connector.

h, the tubular projection for entering the hot-air,

pip

z' the web that connects the tube and the box or r ctangular part of the coupling; these parts f f, g g, 72-, and '5 being cast in one piece, and so that the coupler and register may he sold as one, ready for direct connection of the pipe and register, without any fitting of parts or other than the work ot the most ordinary workman. V

The side flanges of the register preferably fit into the coupling, and the end flanges down upon the top of the coupling-flange; and they may be further connected, if necessary, by any suitable ihsteniugs.

let an denote the register-blades or valves, each having end-center pivots or journals a, which are supported and turn in pivot-holes 0, made in journalplates p in the ordinary manner.

Each blade. has, at one end, a stud, g, projecting into a hole-o3, in a slide or mover, s, that is actuated by the segment-lever t, a stud, a, on the slide,

extending into a slot, 2*, in the lever, in the usual manner.

The segment'lever-is pivoted, seen at to, directly upon the adjacent journal n of the center blade Z, and turns said journal as a fulcrum, so that no screw has to be, applied to form such fulcrum and secure the lever in position, the lever moving more readily, as it is free from the pressure of the screw.

With a four or even-numbered blade-register I cast the pivot as a. stud or projection from the center of 2. The cast-menu coupling 0r connector, having the thejournai-plate. tube h, flanges f g, and web iformed-in one piece, I claimsubstantially as shown and described. V 1.
